This paper is mainly comprised of two components:preparation of models of rats suffering from deficiency of spleen Yang;comparison of the pharmacodynamics impacts of different Lizhong Pills formulations made up by dried ginger or its different components in Lizhong Pills to the different groups of the models.1 Establish the model of deficiency of spleen YANG induced by " cypsum fibrosum and anemarrhenae " with complex factors1.1 ObjectivesWith using heat-clearing and fire-purging drug cypsum fibrosum and anemarrhenae,insteading of the common usage of rhubarb and folium sennae,accompanied with irregular diet and overstrained,the model of deficiency of spleen-YANG is to be established,which is much close to the pathopoiesis theory of " frigidity and chilly damaging yang,irregular diet injuring qi,overstrain impairing the spleen" in TCM.1.2 MethodsModel rats is fully fed every other day,given the molding drug of cypsum fibrosum -anemarrhenae(concentration 4:1) with 3 different frequency,and arranged to swim everyday in 25℃water until exhausted(performing as spitting bubble 3 times continuously or sinking unable to float by itself).

全文共分为脾阳虚模型的制备和干姜及其成分对理中丸药效学影响的比较两大部分。1"石膏-知母"复合法脾阳虚模型的制备1.1目的以清热泻火药石膏-知母代替常用的大黄、番泻叶类苦寒泻下药，并结合饥饱失常、劳倦过度的方法进行造模，以期建立更符合中医"寒凉伤阳、饥饱伤气和劳倦伤脾"致病思路的中医脾阳虚证候模型。1.2方法模型动物隔日足量喂食，每日在25℃水中游泳，直至大鼠连续三次吐泡下沉，或沉入水底，3秒内不能自行浮出水面，并以三种不同给药频率灌胃给予石膏一知母煎液，比较石膏-知母不同给药方法对制备脾阳虚模型的影响。

From Rusticus I received the impression that my character required improvement and discipline; and from him I learned not to be led astray to sophistic emulation, nor to writing on speculative matters, nor to delivering little hortatory orations, nor to showing myself off as a man who practises much discipline, or does benevolent acts in order to make a display; and to abstain from rhetoric, and poetry, and fine writing; and not to walk about in the house in my outdoor dress, nor to do other things of the kind; and to write my letters with simplicity, like the letter which Rusticus wrote from Sinuessa to my mother; and with respect to those who have offended me by words, or done me wrong, to be easily disposed to be pacified and reconciled, as soon as they have shown a readiness to be reconciled; and to read carefully, and not to be satisfied with a superficial understanding of a book; nor hastily to give my assent to those who talk overmuch; and I am indebted to him for being acquainted with the discourses of Epictetus, which he communicated to me out of his own collection.

从拉斯蒂克斯，我领悟到我的品格需要改进和训练，知道不迷误于诡辩的竞赛，不写作投机的东西，不进行繁琐的劝诫，不显示自己训练有素，或者做仁慈的行为以图炫耀；学会了避免辞藻华丽、构思精巧的写作；不穿着出门用的衣服在室内行走及别的类似事件；学会了以朴素的风格写信，就像拉斯蒂克斯从锡纽埃瑟给我的母亲写的信一样；对于那些以言词冒犯我，或者对我做了错事的人，一旦他们表现出和解的意愿，就乐意地与他们和解；从他，我也学会了仔细地阅读，不满足于表面的理解，不轻率地同意那些夸夸其谈的人；我亦感谢他使我熟悉了埃比克太德的言论，那是他从自己的收藏中传授给我的。

It is proved that every Lie derivation of nest algebra is the sum of an associative derivation and a general trace. Every Lie isomorphism between nest subalgebras of a factor von Neumann algebra is the sum of an isomorphism and a general trace or the sum of a negative anti-isomorphism and a general trace. Lie invariant subspace of linear mappings on Banach algebras is introduced, and linear maps from nest subalgebra of a factor von Neumann algebra into itself which satisfy the property that the space of derivations is their Lie invariant subspaces are characterized. Simultaneously, it is shown that such maps are Lie derivations modulo the set of scalar multiple of the identity.

得到Lie导子的特征表示，即套代数上的任何一个Lie导子都是内导子与广义迹之和；给出了Lie同构和同构及反同构之间的关系，即因子von Neumann代数中套子代数之间的任何一个Lie同构要么是同构与广义迹之和要么是负反同构与广义迹之和；引入了Banach代数上线性映射的Lie不变子空间，并给出von Neumann代数中套子代数上以导子空间为Lie不变子空间的线性映射的一个刻画，同时也表明在模去数乘恒等映射的意义下，以导子空间为Lie不变子空间的线性映射就是Lie导子。

In order to replace theinconvenient alternate conduct of drawing and calculating, improvement hasbeen introduced into the paper which means all work can be done bycomputer. Capacity calculation cannot be done without boundary layer build-up. Fit every area curve and area moment curve is necessary because ofinterpolation.
